The more energy stored, or more kilowatt-hours (kWh) or megawatt-hours (MWh), the longer the battery can supply power. Power rating or power capacity is the maximum rate at which the battery can discharge or charge, measured in kilowatts (kW) or megawatts (MW). Its normally determined by the capacity the battery system’s power conversion equipment.
A current of 1Amp or 1000mA will circulate through it as 5V is the standard USB output. The voltage is monitored with a voltmeter for a determined number of hours according to the power bank capacity. If the power bank battery lasts for the same number of hours as listed in the capacity, then it is the actual capacity.
Battery energy storage capacity is the total amount of energy the battery can store, measured in kilowatt-hours (kWh) or megawatt-hours (MWh). Think of this as like the size of a water tank where you measure the water capacity in litres.
Consider a power bank with an energy content of 37 Wh and a capacity of 10 Ah. Compared to the residential battery System A with a capacity six times as large, the energy content of the power bank is as much as 264 times smaller. This is due to the difference in internal voltage, as the power bank battery voltage is only 3.7 V.
